"Tsunami" is the Japanese word composed of two characters "tsu" and "nami" that mean "harbor wave" that is used as a term to describe what scientists call a seismic sea wave. Seismic means an earthquake or earthmoving event. Tsunami are predominately caused by earthquakes that displace large areas of ocean floor and the water above these areas.
Although these deadly masses of water crashing to shore are sometimes referred to as "tidal waves", they have no relation to tides (which are natural movements of the sea level due to the earth's rotation and the pull of lunar gravity).
Storm surge, with effects similar to that of a tsunami, is caused by a severe low-pressure area forming over an ocean area. This low-pressure area (commonly known as a Hurricane, Typhoon, or Cyclone) causes the surrounded water mass to rise up into the eye of the storm. Of course, for storm surge, folks are most concerned with the high winds. But if the storm hits during a period of already high tide, the storm surge can be many meters or feet higher than the protective sea walls and levees and dikes--which results in miles of flooding of any areas near sea level.
